scams. .(ci. 108-8) This invention relates to a roofing strip that can be easily applied. The strip is made up of three .principal parts all firmly attached or adhered together, one of the parts serving as a roofing deck, thus eliminating the necessity of first applying a deck to the rafters, another part serving as a heat insulating layer, and a third part serving as the shingle or water-proof portion of the strip. The strip can be fabricated at the factory and shipped in convenient lengths ready for installation and use.

' The invention will be understood from the description in connection with the accompanying drawing in which Fig. 1 is a plan view, partly broken away, indicating a few of the strips laid one above the other on rafters; Fig. 2 is a transverse section along the line 2-2 of Fig. 1 and Fig. 3 is a transverse section across one of the strips on an enlarged scale.

In the drawing reference character I indicates a roofing strip which is of a length to span the space betweentwo of the rafters 2 or the spaces strips may be installed in such a way that the joints between ends of adjacent strips come in a line or lines down the roof when the strips are not as long as the roof which they cover.

The base or bottom. portion 3 of each strip is made of wood, or other rigid material. When the roofing strips are installed the hases or bottoms Q lie across the rafters with their edges in contact, as indicated in Fig. 2, so that they form a smooth roof deck.

A strip 4 of heat insulating material is applied any convenient cementing material, such as sodium silicate, tar, asphalt, etc. The strip 4 may very advantageously be made to contain or be substantially entirely composed of fibrous material such as sugarcane bagasse, wood fiber, asbestos, etc. The strip 4 is wider than the base 3 to provide a portion 5 which extends beyond the lower edge of the base 3, the top and bottom sides of this extending portion 5 being preferably parallel to each other. The remainder of the strip 4 is preferably made of wedge shape in cross section with the upper edge tapering to a thin portion, as shown at 6.

A strip I of water-proof roofing felt, such as a base of 'felt saturated with asphalt, tar or other bituminous material or the like to render it water-proof, is applied to the top side of the strip 4 of heat insulating material by means of any convenient adhesive or cementitious material. A layer 8 of wear-resisting mineral surfacing,

such as'crushed stone, slate, etc., is applied to a large portion of the upper surface of the strip 1, leaving a portion 9 along the upper edge free from mineral surfacing. The portion 8 that is free from mineral surfacing may have a coating of tar or other water-proof adhesive material applied to'it to cause the next strip above to adhere thereto. "Or copper sheet or other waterproof material may be used as the strip 1.

A water-proof strip I8 is applied along the lower edge of the strip 4 and the lower side of the extending portion 5, as most clearly shown in F g. When the strips l are installed so that there are joints at the ends, as shown in Fig. 1, a strip H of'mineral surfaced roofing felt may be applied over the joints above the rafters where the ends of the strips I meet. The strip Il may be applied by first applying tar, asphalt or other water-proofing adhesive material to the area over which the strip l l is to be applied, or the mineral surfacing 8 may be omitted for short disbetween three or more of these rafters. The tances along the ends of the respective strips I to facilitate application of the Joint breaking strip II, or overlapping shingles may be laid over the joints as the strips are installed.

The strips made in accordance with this invention not only provide a roofing deck andhe'at insulation, as well as the wear-resisting waterproof layer, but the strip is also self spacing due to'the extending portion 5, as will be readily apparent from Fig. 2. Also, by applying ahot iron the asphalt or the like underlying the. mineral surfacing 8 can be made visible so that lines simu- 35 to the base 3 and is made to adhere thereto by la lng he pp r n e f h s can be made along the roof.

' The bottom strip that is to be made along the edge or eave of the roof may be made with the entire portion of the heat insulating strip 4 made wedge shaped and with the base 3 of the same widthas the heat insulating strip, or the bottom strip may be filled in under the portion 5 with a woodstrip or other material similar to that used \for the portion 3, and the hips, valleys, etc., of the roof may be made safe from leakage by applying strips of water-proofing material thereto, or in any other convenient way.

I The portions 4 and 5 of thestrip are advantageously made of material that is not only heat insulating but is also serviceable as sound-proofing material or sound-deadening material, The strips are suitable not only for use as roofing material, but also for sidingas well. Instead of having the joints coming in lines down the roof the joints may be broken and individual shingles the thinner edge of said insulating material toa point short of the other edge thereof and a layer of water proof material extending over the face of said insulating material.

2. A roofing strip comprising insulating material tapering in cross section, a base of uniformly thick stiifened material extending from the thinner edge of said insulating material to a point short of the other edge thereof, a layer of water proof material extending over the face of said insulating material and alayer of water proof adhesive material extending from the terminus of said base portion to the thicker edge of said strip.

3. A roofing and siding strip comprising a base having parallel sides, an intermediate portion of stiff heat insulating material having converging sides and having an extension projecting beyond said base when the two are in assembled relation, a water proof sheet on said intermedate portion, and a water proof sheet extending along the end and under side of said extension.

4. A roofing and siding strip comprising a stifl base having parallel sides, an intermediate portion ,of stiff heat insulating material having converging sides, a water proof sheet on said interthe strips 'mediate portion, and mineral surfacing on the upper surface of said waterproof sheet.

5. A roofing and siding strip comprising a base having parallel sides, an intermediate portion of stiff heat insulating material having converging sides and having an extension with parallel sides projecting beyond said base when the two are in assembled relation, and a waterproof sheet on I said intermediate portion.

6. A roofing and siding strip comprising a base of rigid material having parallel sides, an intermediate portion of stiff heat insulating material having converging sides and having an extension with parallel sides projecting beyond said base when the two are in assembled relation, and a water proof sheet on said intermediate portion.

7. A roofing strip comprising insulating material tapering in cross section, a base of uniformly thick stiffened material extending from the thinner edge of said insulating material to a point short of the other edge thereof and a layer of preformed water proof material extending over the face of said insulating material.

8. A roofing strip comprising a base of uniformly thick stiffened material, insulating material tapering in cross section extending over said base from one edge thereof to the other, an extension of insulating material along the thicker edge of said insulating material having substantially parallel'sides and extending beyond the edge of said base, and a layer of water proof material extending over-the face of said insulating material and said extension.
